摘要： A detection system, and method, for an offshore wellsite (100), the detection system comprising: a wellsite component (127) deployable from a surface rig (106) of a surface system (102) of the offshore wellsite (100) through a conduit (112) of a subsurface system of the offshore wellsite to the subsea BOP, wherein the subsea BOP includes a bore to receive the wellsite component therethrough and a sealing device (126) to seal a wellbore extending from the wellhead; a plurality of axially spaced equipment units (131) disposed along the wellsite component (127); and a plurality of axially spaced base units (133) positioned along the bore of the subsea BOP, wherein each base unit (133) is configured to detect each of the equipment units (131) when the equipment unit (133) is positioned proximal the base unit (133), and wherein the base units (133) are configured to communicate with the equipment units (131) to determine whether one of the equipment units (131) is axially aligned with one of the base units (133) to position the wellsite component (127) in a desired location relative to the subsea BOP.

摘要： A downhole tool comprises a housing having a longitudinal bore and an agitator assembly disposed within the longitudinal bore of the housing. A removable component is disposed within the longitudinal bore and can be removed from the housing so as to at least partially open the longitudinal bore.

摘要： A detection system and method for a well site is provided. The well site has a surface rig and a surface unit. The surface rig is positioned about a formation and a surface unit. The detection system includes a well site component deployable from the surface rig via a conveyance, well site equipment positioned about the well site and having a bore to receive the well site component therethrough; and base units. The base units include scanners positioned radially about the bore of the well site equipment. The scanners detect an outer surface of the well site component and generate combinable images of the well site component whereby the well site equipment is imaged.
